CORPORATION OF PENNSYL- VAC CIN' -POIN 'I'.

To all fr0/tom t may concern.'

Be it known that I, WrLLIAM F. ELGIN, a citizen of the United States, and a resident of Glen Olden, Delaware county, State of Pennsylvania, have invented a Vaccin-Point, of which the following is a specification.

One object of this invention is to provide a so-called point of improved construction which, in addition to being available for use as a scarifier, shall contain a definite quantity of vaccin or serum ;-the invention more particularly contemplating a novel form of scarifier which shall be at all times ready for use as well as simple and inexpensive in construction.

It is further desired to provide a vaccin point with a novel form of package whereby it is at all times maintained in an antiseptic condition and effectually prevented from such movement as would be likely to cause its breakage during transportation.

Another object of the invention is to provide novel means for preventing movement of one or a number of vaccin points within a container during transportation, the invention including also means for keeping said points in an antiseptic condition ready for immediate use.

These objects and other advantageous ends secure as hereinafter set forth, reference being had to the accompanying drawings, in which,

Figure 1 is a vertical section illustrating a package constructed according to my invention, and designed to hold and transport a number 0f vaccin points;

Fig. 2 is a simplified form of the invention designed to include but a single vaccin point; and

Fig. 8 is a vertical section on an enlarged scale illustrating the vaccin point of my invention.

In the above drawings, l represents a length of glass tubing having a body portion 2 and a drawn out thinner part 3 which in the finished article is sealed. The opposite end of said tube is likewise sealed or hermetically closed off and has mounted in it a sharp metal, usually steel, scarifying pin 4, the lower end of the body 2 being preferably provided ywith a transverse notch 5 for the purpose of insuring breakage of the tube at a definite point adjacent its lower end when a suitable breaking stress is applied to it.

Specification of Letters Patent.

Patented July 17, 491'?.

Application filed February 14, 1917. Serial No. 148,514.

The hollow bore G'of the tube contains a greater or less amount of vaccin, serum or the like which may be introduced by any suitable means, and is preferably provided with a discharging bulb 7 of rubber having a neck portion 8 and a centrally placed annular rib 9;-there being openings in its opposite ends, of which Vthat through said neck is designed to receive and closely fit over the reduced end 3 of the tube. The neck 8 is also designed to tightly fit into a narrow elongated container in the form of a closed end glass tube or bottle 10, which under conditions of use, contains a small quantity of an antiseptic substance which may be in liquid, solid or gaseous form. Formalin for example, may be used as such a substance.

Where it is desired that the container shall hold more than one point, I provide a relatively larger bottle or .holder 10a having a neck portion and preferably of the form shown in Fig. l, and Iplace in the bottom of this a body of cotton l1, in which the antiseptic substance is contained. A number of vaccin points arev then placed in the container with their scarifying pins 4 resting upon or extending into a body of cotton or other mass of more or less springy and usually absorbent material 11, the length of said container and the amount of said cotton being such that these points, after their introduction, have little if any longitudinal movement. Another point 1a, with its reduced end 3 inserted in the neck of the bulb 7, is finally placed in the container l0EL and the proportions of the various parts are such that when the ellipsoidal or other suitably tapering portion l2 of the bulb, between its neck 8 and its central rib or flange 9, is forced into the neck 13 of the container, the consequent passage of its pin 4 into or its engagement with the material l1, causes the latter to expand or move upwardly into engagement with the pins 4 of the other points .so as to hold these from subsequent movement. Even though the container may thereafter be subjected to comparatively severe shocks, there is no rattling or such movement of the vaccin points as would break or otherwise injure them.

Under conditions of use the bulb 7 with its attached tube l is removed from the container 10 or l0al as the case may be, and the scarifying pin 4 is applied'to the skin of a ypatient so as to abrade or cut into the Same 6.0 the desired extent. Thereafter the scarifier-carryng part or end of the glass tube. is broken at the notch 5 by a bending force exerted by the fingers of the operator, and the reduced end 3 is similarly broken in: sideA theI bulb; 'l' ;-z'., e., Without removing it. from the bulb. i A linger or thumb of the operator is then pressed? over the hole Me at the upper end of the bulb and the latter is compressed, thus forcing out the small quantity off serum or` vaccin Within the tube and permitting it to be applied to or de positedi on the previously scarilied. surface et the pati'entst skin.. l

By the above arrangement el? parts and method et procedure, the point 'is maintained in an antiseptic condition and is not exposed: to the airor openeduntil; after the desired skin surace of the patient has been scari'ii'edf b y the aseptic pin l ofl the point. Thereafter the vaccin- `or- Seru-m i's forced out' o'- the tube Without. danger of contamina-tiona-t; either offitsl ends.,

Ift is;I to be understood that by the term scarifying point asusedin the foregoing description in the claims is meant any structure regardless of its form, which is-suitable7 or lWillich is capable of being used as a means, for abradingf-thefskin for purposes oi inoculation-, l i

` I` claim.;-

A vaccin or similar point consisting of' a sealed; glass tube containing liquid to be administered; and a metal scarifying pin rigidly sealed in one end of said tube.

A vaccin or similar point consisting of a sealed glass tube containing liquid to be administered and having one end portion of reduced section tovpermit'of its relatively easy breakage; with a metal scarifying point rigidly sealed in the opposite end of said tube.

3. The combination of a container formed with an open end; a bulb nermally closing said end ;y and. a plural-ity oli independent vacei'n tubes in, the container oi which one extends into. the bulb so; as to be removable therewith; with a mass o'rellativel'y springy material engaging said peintsy to prevent theirmovement.

4:. The combination of' a container formed withv an openend; a mass` oi relatively spri-n-gyv material in said container; a vaccin point in saieli containerL having one end immovably held by said springy :materiale and means at the opposite end= of' said container for innnovably holding the second end of the vaccin point.

5'. The combination of-a container formed with an open end; a bulb noiunallyf closing saidli end;A a mass of sptingy'materi'al in the container; andl a vaccin point in the container havingits ends'respectively enteringthe springy' materialg and the bulb so as to bel iinmovably held thereby.
